We have been contacted by wgt, and to clarify he was simply distracted and entered 400 into the dollar column instead of the credit column (I thought he had typoed 40,000 instead of 400 which is hard to believe, typing 400 in the wrong column isn't). I have not purchased credits (yet) but if there isn't a "yes/no" confirmation screen after you click the "purchase" button I suggest this be added. Thank you to the WGT staff who contacted us on a holiday weekend. Great game, and great support.
